After commit a97c9bf3 (fix cramfs making duplicate entries in inode cache) in kernel 2.6.14, named-pipe on cramfs does not work properly. It seems the commit make all named-pipe on cramfs share their inode (and named-pipe buffer). Make ..._test() refuse to merge inodes with ->i_ino == 1, take inode setup back to get_cramfs_inode() and make ->drop_inode() evict ones with ->i_ino == 1 immediately. Reported-by:

Fixes kernel BUG at lib/radix-tree.c:473. Previously the handler was incidentally provided by tmpfs but this was removed with: commit 14fcc23f Author: Hugh Dickins <hugh@veritas.com> Date: Mon Jul 28 15:46:19 2008 -0700 tmpfs: fix kernel BUG in shmem_delete_inode relying on this behaviour was incorrect in any case and the BUG also appeared when the device node was on an ext3 filesystem. v2: override a_ops at open() time rather than mmap() time to minimise races per AKPM's concerns.

On a PowerPC board with ds1374 RTC I'm getting this error while RTC tries to probe: rtc-ds1374 0-0068: unable to request IRQ This happens because I2C probing code (drivers/of/of_i2c.c) is specifying IRQ0 for 'no irq' case, which is correct. The driver handles this incorrectly, though. This patch fixes it. Signed-off-by:

XIP can call into get_xip_mem concurrently with the same file,offset with create=1. This usually maps down to get_block, which expects the page lock to prevent such a situation. This causes ext2 to explode for one reason or another. Serialise those calls for the moment. For common usages today, I suspect get_xip_mem rarely is called to create new blocks. In future as XIP technologies evolve we might need to look at which operations require scalability, and rework the locking to suit. Signed-off-by:

XIP has a race between sparse pages being inserted into page tables, and sparse pages being zapped when its time to put a non-sparse page in. What can happen is that a process can be left with a dangling sparse page in a MAP_SHARED mapping, while the rest of the world sees the non-sparse version. Ie. data corruption. Guard these operations with a seqlock, making fault-in-sparse-pages the slowpath, and try-to-unmap-sparse-pages the fastpath. Signed-off-by:

There is a race with dirty page accounting where a page may not properly be accounted for. clear_page_dirty_for_io() calls page_mkclean; then TestClearPageDirty. page_mkclean walks the rmaps for that page, and for each one it cleans and write protects the pte if it was dirty. It uses page_check_address to find the pte. That function has a shortcut to avoid the ptl if the pte is not present. Unfortunately, the pte can be switched to not-present then back to present by other code while holding the page table lock -- this should not be a signal for page_mkclean to ignore that pte, because it may be dirty. For example, powerpc64's set_pte_at will clear a previously present pte before setting it to the desired value. There may also be other code in core mm or in arch which do similar things. The consequence of the bug is loss of data integrity due to msync, and loss of dirty page accounting accuracy. XIP's __xip_unmap could easily also be unreliable (depending on the exact XIP locking scheme), which can lead to data corruption. Fix this by having an option to always take ptl to check the pte in page_check_address. It's possible to retain this optimization for page_referenced and try_to_unmap. Signed-off-by:

When user calls sys_setpriority(PRIO_PGRP ...) on a NPTL style multi-LWP process, only the task leader of the process is affected, all other sibling LWP threads didn't receive the setting. The problem was that the iterator used in sys_setpriority() only iteartes over one task for each process, ignoring all other sibling thread. Introduce a new macro do_each_pid_thread / while_each_pid_thread to walk each thread of a process. Convert 4 call sites in {set/get}priority and ioprio_{set/get}.

Absolute alignment requirements may never be applied to node-relative offsets. Andreas Herrmann spotted this flaw when a bootmem allocation on an unaligned node was itself not aligned because the combination of an unaligned node with an aligned offset into that node is not garuanteed to be aligned itself. This patch introduces two helper functions that align a node-relative index or offset with respect to the node's starting address so that the absolute PFN or virtual address that results from combining the two satisfies the requested alignment. Then all the broken ALIGN()s in alloc_bootmem_core() are replaced by these helpers. Signed-off-by:

With commit 5ad31a57 ("rtc: remove BKL for ioctl()"), RTC_UIE_ON ioctl cause double lock on rtc->ops_lock. The ops_lock must not be held while set_uie() calls rtc_read_time() which takes the lock. Also clear_uie() does not need ops_lock. This patch fixes return value of RTC_UIE_OFF ioctl too. Signed-off-by:

In case the binfmt_misc binary handler is registered *before* the e.g. script one (when for example being compiled as a module) the following situation may occur: 1. user launches a script, whose interpreter is a misc binary; 2. the load_misc_binary sets the misc_bang and returns -ENOEVEC, since the binary is a script; 3. the load_script_binary loads one and calls for search_binary_hander to run the interpreter; 4. the load_misc_binary is called again, but refuses to load the binary due to misc_bang bit set. The fix is to move the misc_bang setting lower - prior to the actual call to the search_binary_handler.

Add a comment to s390's page_test_dirty/page_clear_dirty/page_set_dirty dance in page_remove_rmap(): I was wrong to think the PageSwapCache test could be avoided, and would like a comment in there to remind me. And mention s390, to help us remember that this block is not really common. Also move down the "It would be tidy to reset PageAnon" comment: it does not belong to s390's block, and it would be unwise to reset PageAnon before we're done with testing it. Signed-off-by:

I won't say 'fix', because they still look broken, although this will at least allow 'make ARCH=CRIS headers_install' to _complete_. For headers which are exported, we should probably choose between asm/arch-v10 and asm/arch-v32 by something that GCC defines -- we can't rely on a generated symlink. And we certainly can't export an arch/ directory which doesn't even exist. And the only thing that we seem to include from the arch/ directory is <asm/arch/ptrace.h> from <asm/ptrace.h> ... and that isn't exported in either arch-v10 or arch-v32 _anyway_. Signed-off-by:

There was another FAT BKL conversion deadlock reported by Bart Trojanowski due to the BKL being used as a recursive lock by FAT, which was missed because it only triggers with 'sync' (or 'dirsync') mounts. The recursion worked for the BKL, but after the conversion to lock_super (which uses a mutex), it just deadlocks. Thanks to Bart for debugging this and testing the fix.

The lock_super() there had been just an automatic conversion of the kernel lock to the superblock lock, but no locking was actually needed there, since the code in fat_write_inode already protected all relevant accesses with a spinlock (sbi->inode_hash_lock to be exact). The only code inside the BKL (and thus the superblock lock) was accesses tp local variables or calls to functions that have long been SMP-safe (i.e. sb_bread, mark_buffe_dirty and brlese).
